Er, you might try advancing the cam timing 4 degrees? :)
I did that to my '91 Bronco 351w, ZF swap, 3.55 gears with 265/85-16E's
~32 inch tires. I'm going to 3.73 gears as soon as I can and that change
will make it feel like 30 to 30.5 inch tires.
What the cam timing change did was made it feel less-powerful because
it got rid of its "pipey hit". So, that made it less-fun to drive in a way, but
made it a much better travel-rig and grocery-getter tho. :)
It can pull pretty good from 35mph now in 4th gear (1:1). :)
Before there were too many speeds/situations where there was no-right
gear to be in. :/ It sucked for everything except when it was on-the-pipe
-and- I wanted to floor it.
I don't recommend this 4* cam timing advance for automatics.

That and the 205* thermostat change, upped my gas mileage. The old
thermostat was a 195*F but it was bad and acting more like a 180*. :/
The new thermostat was supposed to be 195* but tested out at 205*.
The bad thermostat was new too, but I didn't test it! :(
Before blaming everything on Ford, it's best to make sure everything is
right on your particular 351w first.
on the same token, if you're wanting diesel power, you're gonna be unhappy with anything but a diesel. I'm a straight six guy through and through. and I love my 4.9. On the other hand, I also love the 5.9 cummins in my super duty (another straight six...). The 7.3 is the last true diesel ford sent out before the 6.7...
Find an OBS with forged rods and do the swap. Nothing else will ever give you the satisfaction you want...
I know this guy with a 7.3 thats running great that'd be open to a cheap sale, or the right trade... And I'm, I mean he's, easy to get a hold of most of the time too. If you want true power potential don't let go of your goal, and get the diesel. If you want the best all around bronco for your lower dollar, build the 351. If you want dead reliable and simple, do the six. they're all good choices. which do YOU want?
95 F-250, 7.3L, E40D - 300,000 miles
80 Bronco, 300c.i. inline, NP435 - 180,000 miles
83 F-150, 300c.i. inline, NP435 - 310,000 miles
Well, I was madly in love with the 400 in my F150.. I wish they had fuel injected it AND gas was $2 a gallon, I'd swap one in my Bronco in a heartbeat.
Thinking about it, the 300 is basically a 400 with two fewer cylinders. I bet I'd love a 300 stroker... ill probably do it one day, supercharge a 300 stroker.. after I marry a supermodel and make my millions, ya know.
but these are big trucks, as strong and big as it is for a 6 cylinder, it's still only a 6 cylinder. (edit: I should have said, it's still only 300ci instead of 'only 6 cylinder'!)
Anyways, putting money into any motor is never a bad thing. I imagine the 300 with a few grand in performance parts would make for one heck of a motor.
Like I said, if only Ford had made a 4'' bore, 4'' stroke 8 Cylinder motor for us truck people, it would have been awesome.. I think we all would have appreciated it? Who cares about horsepower as truck people anyways! I know for a fact it would have been a huge hit! hmmm (and yes, that was sarcasm :P)
Check with the boys at FordSix. They will tell you that you aren't gonna get any significant increase in stroke out of a 300. Boring it over there is actually a good bit of room as I understand it without risking "hot spots".
Yes, it would have been nice... closest they ever came in a gaser was the 460.
Now my Cadi's had 472's and those had 4.30" bore and 4.06" stroke and would kick a 6800 lb. car in the @$$ and send it down the freeway like a rocket even if the A/C was running full tilt and you had six people in the car. In '68 when they were introduced the CR was damned near high enough to run them on propane at 10.5-1.
